Patent DE-3034543-A1 (DE)
Title: Determining quality classification esp. of timber radiographically - using summated values of readings over a specified zone
Inventor: WIESNER LOTHAR DR
IPC: G01N33/46
Filed: 1980-09-12
Abstract: The quality of single-layer or multi-layer materials, esp. sawn timber, planks, logs beams etc., is determined without contact using continuous ionising radiation, the material being classified as a function of the quantity of radiation converted into a measuring signal after passing through the material. One criterion used is the summated count value resulting from one complete measuring operation, of the deviations of the measured value from a basic value corresp. to faultless material. Pref. the deviations of cross-sections of the timber contg. knots are associated with those of knot-free sections and the summated value of the deviations is formed from the max. differences between the basic measured value and the deviated measured values. Used esp. for the classification of sawn, structural timber members. The method provides accurate measurement and evaluation and is almost independent of sorting speed.
Patent DE-3038579-A1 (DE)
Title: Room heating system with heat pump - stores surplus heat in stages for long periods on cold side
Inventor: KRIEB FRANZ KARL
IPC: F24D19/10
Filed: 1980-10-13
Abstract: The heating system uses heat from any source such as the environment or a power station, this being directly used or briefly stored as long as its temperature is sufficient, and otherwise raised by heat pump to the desired temp. For later use, the surplus heat is stored for a long period on the cold side of the heat pump in one or more temp. stages, the heat losses from the high-temp ones being absorbed by the low-temp. ones. After increasing the temp. of the transfer fluid by extraction from the first stage, heat extraction then takes place from others whose temperatures increase in stages. Heat is transferred from some of the stages to the earth for long-term storage. When extracting heat from the lower-temp. stages the medium is converted from the liquid to the solid state and all its latent heat thus used, heat flowing in from the warmer surrounding earth. Heat is stored so as to allow extraction and temp. increases by heat pump for peak loads, this being done at low load times of the power station, storage then taking place in short-term accumulators at the supply temp. of the heating system.

Title: Measuring play in vehicle coupling release mechanisms - using displacement transducer on release lever and compensated measurement circuit
Inventor: ASHAUER KARL ING GRAD
IPC: G01B7/14
Filed: 1980-11-14
Abstract: The arrangement for measuring the play in coupling disengagement devices is applicable to vehicle couplings with release bearings (2) and levers (4) normally held in output positions by springs. They enable very objective measurement and esp. enable reduction of the subjective inaccuracies dependent on the test operator. When the device which removes the contact region (9) from the release bearing (2) is operated an electrical null point measurement signal is generated. The distance between the positions of the contact region on removal from the bearing and when the lever reaches its output position is measured electrically. A displacement measurement transducer (13) is clamped to the coupling release lever (5). It is connected to a measurement circuit with compensation for the signal produced on removal.

Title: Wood thermo:grinder - has throttle valves in outlet channel to maintain trough level
Inventor: BAEHR THEODOR
IPC: D21B1/24
Filed: 1980-12-05
Abstract: The outlet channel for the ground wood material and fluid is fitted with throttle valves. They are so controlled that one throttle valve is operated repeatedly during a given time span, while the other throttle valve is operated separately during a subsequent time span, each throttle acting alone in each case. Thus the level of the material in the trough is held at a constant level, at least at its outlet, and the pressure in the housing is also maintained at the required level. The system ensures that the pressure is maintained for thermo-grinding of wood, that the wood and fluid are extracted without clogging, and that the wood chips can be graded.

Patent DE-3048732-A1 (DE)
IPC: G05D16/06
Filed: 1980-12-23
Abstract: Valve means for the withdrawal of gas, at a low pressure suitable for a domestic appliance from a high- pressure vessel (11) includes a main closure valve (13) for connection to the vessel (11). The valve (13) has a displaceable closure element (22) which is actuated by a tappet (81) which is connected to the spring- loaded diaphragm (76) of an attached reducing valve (14). When the pressure of gas at the outlet side falls, the diaphragm (76) deforms, thus moving the tappet (81) to cause displacement of the closure element (22) to open the main valve (13). The reducing valve (14) may be installed at the lower end (92) of a receiving chute (91), in which a gas cylinder (11) with the main valve (13) attached is slidable downwards, to cause engagement of the main (13) and reducing (14) valves by means of a simple push-in connection. <IMAGE>

Title: Refrigerator or the like for recreational vehicles, caravans and similar
Inventor: LATTEK HORST
IPC: G05D23/19
Filed: 1981-08-26
Abstract: The invention relates to refrigerators or the like for recreational vehicles, caravans and similar, for operation by alternating current, direct current or liquefied gas. Those appliances of the prior art which are relevant to this field have considerable shortcomings in function and control, such as an elaborate control system of up to 6 control elements which have to be changed over manually between the operating modes corresponding to the different types of power, and operation which is not free of interruption and is only partly controlled by thermostat and hence different temperatures of the goods to be cooled. The arrangement and design, according to the claim, of the switching and monitoring elements (4, 5, 6) bring about a simple control system with a maximum of two control elements - main switch (4) and thermostat (5) and operation which is free of interruptions, i.e. automatic selection of power between alternating current (1), direct current (2) and liquefied gas (3), and changing over of the operating mode to the associated function elements - (7) for alternating current, (8) for direct current and (9) for liquefied gas, resulting in cost-effective operation and by means of a central thermostatic control, in a constant temperature for goods being cooled. The main area of use is in recreational vehicles, caravans and similar, in particular recreational vehicles and motor homes which due to their design require the mentioned operating mode changeover for the operation of the refrigerator. <IMAGE>
